### `method` include_router

Include a router's tools, resources, and prompts into this server.

        Similar to FastAPI's include_router, this allows you to organize your
        MCP server into multiple files/modules.

        Example:
            ```python
            from mcp_use.server import MCPServer, MCPRouter

            # In routes/math.py
            router = MCPRouter()

            @router.tool()
            def add(a: int, b: int) -> int:
                return a + b

            # In main.py
            server = MCPServer(name="my-server")
            server.include_router(router, prefix="math")  # Tool becomes "math_add"
            server.include_router(other_router, enabled=False)  # Skip this router
            ```


**Parameters**
><ParamField body="router" type="MCPRouter" required="True" >   The MCPRouter instance to include </ParamField>
><ParamField body="prefix" type="str" default='' >   Optional prefix to add to all tool names (e.g., "math" -> "math_add") </ParamField>
><ParamField body="enabled" type="bool" default="True" >   Whether to enable this router (default True). Set to False to skip registration. </ParamField>

**Signature**
```python wrap
def include_router(router: MCPRouter, prefix: str = "", enabled: bool = True):
```
